No sound: main.c: pa_pid_file_create() failed

Question

I'm not able to use pulseaudio so no sound at all in Ubuntu 19.04 and my laptop is Lambda Tensorbook. Anyone could help me to fix this "headache"? Thanks at advance.

Solution

If you have updated pulseaudio recently or restored old home directory or configuration files, you could try:

rm  ~/.config/pulse/*

This should remove your current defaults for pulseaudio which are apparently not working.

After this, please reboot your system to build new pulseaudio configuration files.

ps -ef | grep pulse and snap list please

I have updated the output of your command. Please check.

Hi, were you able to solve this problem? it's been 5 days i can't fix it

[ah bon]

@HabibRehman I remeber I‘ve sent an email to Lambda Labs, Inc., and the client service sent me a command: echo "options snd_hda_intel probe_mask=1" | sudo tee /etc/modprobe.d/tensorbook.conf sudo update-initramfs -u -k all then reboot, I remeber it worked out (not sure for your case it will works out or not, hope it helps). However, I reinstall another system named pop_os later.

[Habib Rehman]

@ahbon, thanks i'll check this out

[ah bon]

Thank you very much. I remove x@x:~/.pulse$ locate default-sink /home/x/.config/pulse/a780a212b2e84b5f8f2f3abe253cfbbb-defau‌​lt-sink /home/x/.pulse/a780a212b2e84b5f8f2f3abe253cfbbb-default-sink‌​, then should I reboot?

[Raffa]

Yes, please reboot

[ah bon]

OK, I try with that and let you know what happens. BTW, just wonder why there two .pulse path for *default-sink, it's confusing, should I remove one?

[Raffa]

better to remove all files in that directory and reboot. They will be rebuilt after reboot. run rm ~/.config/pulse/* and reboot

[Raffa]

In your case. Please delete all the files in /home/x/.config/pulse/ only.

x@x:/etc/ld.so.conf.d$ ls cuda-10-1.conf fakeroot-x86_64-linux-gnu.conf i386-linux-gnu.conf libc.conf x86_64-linux-gnu.conf

[Joergi]

fixed it for me. Just deleting the files and then a restart did it.
